Abstract (en)
[origin: US2022003081A1] A fluid control device includes a filtration component, which has a porous filtration medium. The filtration medium contains a shape memory thermoset material foamed with a polymeric microsphere and a gas-producing chemical foaming agent. The porous filtration medium is configured to be compacted from an initial shape to a compacted shape, deployed in the borehole, and subsequently expanded to conform to a surface of the borehole.
